correction* 3 meters is too less room.

*July 22, 2008*

**Math**

Okay. That's true, 3 meters is a pretty wide space. I figured out the first dimension, it's 29.8 m. I still need the second dimension so I can figure out the area of the fenced space.

A tennis court is 23.8 m by 11 m. A tennis club has 3 courts side by side in a fenced area. The courts have 3 m between them and 3 m around the outside. What are the dimensions of the fenced space? Please and thank you!

Okay. Thank you very much. I had a feeling that the answer at the back was wrong, I tried many solutions, and it didn't work. So you're probably right. :)

The question says that the diameter is 8 cm, and then it asks to fnd the perimeter. I found the answer using your formula but when I checked the back of the book, it said the answer was 20.56 cm, not 25.12 cm.

correction..: how would you solve this equation? the height of a triangle is 2m more than the base. The area is 17.5m^2. Find the length of the base. it's height.. not measurement..
